Does "ColorWare" make an iPhone 5s warranty (AppleCare) invalid?

I have found a web sight called ColorWare (, and i am really tempted to get my iPhone 5s painted. But, i really am wondering if it would make my iPhone not valid to the warranty? I'm just nervous i would crack my phone screen or something, and when i take it in they would say it is not covered under warranty (because i got it "colorwared").
